At 1920x1200, GTX 460 768MB in SLI (reference clocks) outruns a single GTX 480 by 6%, whereas switching to Superclocked clocks more than doubles this advantage – 16%. GTX 460 768MB in SLI gives about 90% better performance compared to a single card.

We didn’t increase the resolution to 2560x1600 in Metro 2033, but rather switche graphics settings from “high” to “very high”.
